The Naval Air Warfare Center Aircraft Division, Lakehurst is seeking contractors to participate in a joint partnership with the Navy to improve the productibility and manufacturability of the Improved Fresnel Lens Optical Landing System (IFLOLS). The IFLOLS is a visual landing aid to be installed aboard the United States Navy Aircraft Carriers that provides glideslope guidance to the pilot of an approaching aircraft. The following are major components of the IFLOLS: Indicator Assemby: Consists of glass lens assemblies, stabilized fiber optic blocks and microprocessor controlled drive system (DC motor, ballscrew, and linear slide assembly). Requires highly accurate machining to maintain the tight tolerance specified throughout. Dimensions: 73'' x 17''W x 42''D. Weight 1340 lbs. Lens Room Electronic Enclosure: Consists of touch screen display, fiber optic communication hub (to communicate with 2 other remote panels via ethernet), card cage assembly (12 printed circuit boards of SEM 'D' and 'E'formats) and motor driven variacs for source light intensity control. Dimensions: 53''H x 30''W x 58''D. Weight 200 lbs. Heave sensor: Consists of 3 accelerometers mounted to an accurately machined base plate. Dimensions: 12''H x 5''W x 13''D. Weight 20 lbs. Datum Arm Structure: Consists of welder tubular structure, machined lamp housing and lamp assemblies. Dimensions: 50''H x 27''W x 70''D. Weight 100 lbs. Lamp Arm Structure: Consists of welded and machined tubular structure and lamp housing assemblies. Dimensions: 57''H x 33''W x 40''D. Weight 120 lbs.

The Navy will host a pre-solicitation meeting in the April/May time frame, where the IFLOLS program will be presented to perspective contractors. This RFI supersedes N68335-96-RFI-601 of December 26, 1995. This is not a request for proposal, but rather a request for interested contractors who wish to be notified of the time and place of the pre-solicitation meeting. The Government does not intend to award a contract from this RFI and will not pay for any information submitted. Response is requested by 14 Feb 96.
